Ventoinha Jonsbo ZB-240 240mm ARGB PWM preta — design Infinity-Mirror

Jonsbo ZB-240 is a 240 mm black cooling fan designed for PC case and radiator installation. It combines ARGB lighting with PWM speed control and an Infinity Mirror design to deliver adjustable illumination and variable airflow. The fan targets system builders and upgraders who need controlled cooling performance with customizable, synchronized lighting effects.

Advantages

The fan offers PWM control for automatic speed adjustment according to system temperature, helping to balance cooling efficiency and noise levels. Integrated ARGB lighting with an Infinity Mirror effect provides deep, layered illumination that is compatible with standard 3-pin ARGB controllers and motherboard software. The 240 mm form factor supports higher airflow at lower RPM compared with smaller fans, enabling quieter operation under typical loads.

Suitable for

• PC case cooling for mid-tower and full-tower systems
• Radiator mounting in liquid-cooling loops using 240 mm radiators
• Custom builds where synchronized ARGB lighting is required
• Systems prioritizing quiet operation with adjustable fan speed

Key specifications

• Fan size: 240 mm diameter
• Lighting type: Addressable RGB (ARGB) with Infinity Mirror design
• Speed control: PWM (pulse-width modulation) compatible
• Frame color: Black
• Mounting: Standard 240 mm fan/radiator mount pattern

How to use

Install the fan in a supported 240 mm mounting location inside the PC case or on a compatible radiator using the supplied mounting screws. Connect the power cable to a PWM-compatible fan header on the motherboard or to a PWM fan hub for automatic speed regulation. Attach the ARGB connector to a compatible 3-pin ARGB header or controller to enable lighting control and synchronization. Verify cable routing to avoid interference with other components and ensure unobstructed airflow.

Recommendations

For optimized cooling and quiet operation, enable motherboard PWM control and configure fan curves in BIOS or system software. Use an ARGB controller or motherboard software that supports addressable RGB to access full lighting effects and synchronize the Infinity Mirror visuals with other system lighting.
